Product and manufacturing information
Product and manufacturing information, also abbreviated PMI, conveys non-geometric attributes in 3D
Uses and visualization
The PMI annotation is created on the 3D CAD model, associated to edges and faces, and can be exported into neutral formats such as
PMI items are often organized within annotation views. Annotation views typically view including camera/view position, selected and also the particular state of the assembly (visibility, rendering mode, sometime even position of each element of the assembly). CAD applications have different notions of PMI Views (for instance "Capture Views" and "Annotation Views" are specific to Dassault Systems CATIA, etc.).
For anyone to be able to display any kind of PMI View,
Communication deliverables
In an effort to unify the visualization of PMI across the different existing solutions,
The ISO 10303 STEP standards also handle a wide range of PMI information. ISO 10303 is an ISO standard for the computer-interpretable representation and exchange of product manufacturing information. It is an ASCII-based format.[1]: 59 Its official title is: Automation systems and integration — Product data representation and exchange. It is known informally as "STEP", which stands for "Standard for the Exchange of Product model data". ISO 10303 can represent 3D objects in Computer-aided design (CAD) and related information.
